Genetically Boosting Electron Transfer in Electroactive Biofilms for Improved Sensitivity of Microbial Fuel Cell‐Based Biosensing

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Engineering Geobacter biofilms through the manipulation of the cyclic GMP‐AMP signalling system led to the formation of thin, highly conductive bioanodes. This boosted extracellular electron transfer, enabling a microbial fuel cell biosensor with a 20‐fold lower Cd(II) detection limit (0.03 mg L−1) by increasing cytochromes/nanowires and reducing ...

Expanding the Diet for DIET: Electron Donors Supporting Direct Interspecies Electron Transfer (DIET) in Defined Co-Cultures

Frontiers in Microbiology, 2016
Direct interspecies electron transfer (DIET) has been recognized as an alternative to interspecies H2 transfer as a mechanism for syntrophic growth, but previous studies on DIET with defined co-cultures have only documented DIET with ethanol as the ...

Production of gold nanoparticles by electrode-respiring Geobacter sulfurreducens biofilms [PDF]

Enzyme and Microbial Technology, 2016
The goal of this work was to synthesize gold nanoparticles (AuNPs) using electrode-respiring Geobacter sulfurreducens biofilms. We found that AuNPs are generated in the extracellular matrix of Geobacter biofilms and have an average particle size of 20nm. The formation of AuNPs was verified using TEM, FTIR and EDX.

Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...

Electricity Generation by Geobacter sulfurreducens Attached to Gold Electrodes

Langmuir, 2008
The versatility of gold for electrode manufacture suggests that it could be an ideal material for some microbial fuel cell applications. However, previous studies have suggested that microorganisms that readily transfer electrons to graphite do not transfer electrons to gold.

Elucidation of an Alternate Isoleucine Biosynthesis Pathway in Geobacter sulfurreducens [PDF]

Journal of Bacteriology, 2008
ABSTRACT The central metabolic model for Geobacter sulfurreducens included a single pathway for the biosynthesis of isoleucine that was analogous to that of Escherichia coli , in which the isoleucine precursor 2-oxobutanoate is generated from threonine.
